* This is the base series prototype that all other series types inherit from.
* A new series is initialized either through the
* [series](https://api.highcharts.com/highcharts/series)
* option structure, or after the chart is initialized, through
* {@link Highcharts.Chart#addSeries}.
*
* The object can be accessed in a number of ways. All series and point event
* handlers give a reference to the `series` object. The chart object has a
* {@link Highcharts.Chart#series|series} property that is a collection of all
* the chart's series. The point objects and axis objects also have the same
* reference.
*
* Another way to reference the series programmatically is by `id`. Add an id
* in the series configuration options, and get the series object by
* {@link Highcharts.Chart#get}.
*
* Configuration options for the series are given in three levels. Options for
* all series in a chart are given in the
* [plotOptions.series](https://api.highcharts.com/highcharts/plotOptions.series)
* object. Then options for all series of a specific type
* are given in the plotOptions of that type, for example `plotOptions.line`.
* Next, options for one single series are given in the series array, or as
* arguments to `chart.addSeries`.
*
* The data in the series is stored in various arrays.
*
* - First, `series.options.data` contains all the original config options for
* each point whether added by options or methods like `series.addPoint`.
*
* - Next, `series.data` contains those values converted to points, but in case
* the series data length exceeds the `cropThreshold`, or if the data is
* grouped, `series.data` doesn't contain all the points. It only contains the
* points that have been created on demand.
*
* - Then there's `series.points` that contains all currently visible point
* objects. In case of cropping, the cropped-away points are not part of this
* array. The `series.points` array starts at `series.cropStart` compared to
* `series.data` and `series.options.data`. If however the series data is
* grouped, these can't be correlated one to one.
*
* - `series.xData` and `series.processedXData` contain clean x values,
* equivalent to `series.data` and `series.points`.
*
* - `series.yData` and `series.processedYData` contain clean y values,
* equivalent to `series.data` and `series.points`.
